The team around the East Side Coastal Resiliency (ESCR) project in New York is growing. CH2M, a consulting firm in Colorado, USA, is chosen by New York’s City Department of Design and Construction (DDC) to support upcoming design activities in the development, approval and implementation phases.
The East Side Coastal Resiliency project is a result of Hurricane Sandy in October 2012. After this disastrous flooding, higher demands were voiced to increase flood protection and resiliency. Thus, as a mitigation measure, this integrated coastal protection system is intended to protect against future floods. Additionally, the project should be accompanied by a fundamental redesign of the waterfront with open access and offer additional recreational spaces for everybody.
Construction start for the East Side Coast Resiliency Project is planned for late 2017
CH2M’s Project Manager Jonathan Goldstick states: “Our engineers have been working on the City’s waterfront for more than 35 years and have extensive experience addressing sea level rise and climate adaptation. We’re looking forward to partnering with the DDC to integrate flood protection into the community fabric of Manhattan.”
The coastal project starts from Montgomery Street and ends at East 25th Street in Lower Manhattan. In order to strengthen New York’s coastal defenses against flooding, sea level rise and other climate-related hazards, different physical and social resiliency measures will come into play. This so-called application of a multi-barrier system approaches the problem in a number of ways. Various (=multi) types of measures (=barrier) will either eliminate or minimize their impact.
The following examples give some ideas of possible barrier options.
- A storage tank in East River Park will manage sewer overflows.
- Inland flooding management will consider pumping and storage alternatives.
- Planned floodwalls, marginally moved towards inland, leave the park open and provide larger capacities to store water in case of a flood.
- Planted embankments provide green and recreational space.
- Vigorous plants on the embankment’s surface protect against flood erosion.
- Plants and trees will also be robust against salt water.
Apart from the protective characteristics, public space, outdoor gathering, and waterfront accessibility are still all in focus. Furthermore, it is intended to ensure the access to the parks and coastal sections. Only during the construction period, the access will understandably be limited. Expenditures for design and construction will be funded by a federal grant of $335 million compiled by the city, state, and federal agencies.
